Concentrates Some background on the CBD → THC conversion

This seemed worth sharing here:

Converting CBD to Δ9-THC has been studied since the 1940’s when Adams et al. determined that acid would catalyze the reaction of converting CBD to other psychoactive cannabinoids.

It's fairly straightforward to convert CBD isolate into [various isomers of] THC with common acids used for baking cakes. But this thread is about CBD converting to THC when ingested:

It is well known that CBD will convert to other known cannabinoids such as Δ8-THC, Δ9-THC, and CBN when adding acid to the CBD. This conversion of CBD to Δ9-THC using hydrochloric acid prompted a large field of research to determine if CBD could be converted to Δ9-THC during the digestion process due to a large amount of hydrochloric acid in the stomach. Other research groups have found that Δ9-THC does get formed in the stomach as well as other cannabinoid metabolites such as 6β-hydroxymethyl-Δ9-tetrahydrocannabinol. This metabolite, 6β-hydroxymethyl-Δ9-tetrahydrocannabinol, has similar psychoactive properties as Δ9-THC.

Hm conversion in vivo to THC must be not that significant. I never felt any THC like effect when ingesting CBD tinctures, allthough I never pushed the dose.
